Specification of Letters Patent.

Patented June 26, 1906.

Application filed November 26,1905. Serial No, 289.052.

To all whom it may concern: I

Be it known that I, D McRA LIvINosToN, a citizen of the United States, and a resident ofthe cit of New York, borough of Manhattan, int e county and State of New York,

. have invented a new and Improved Cooler or to present a diamond Similar Apparatus, of which the following is a full, clear, and exact description.-

The, invention is principally intended forembodiment in the coolers of motor-vehicles propelled by explosive-engines, and the present invention relates especially to that form of cooler inwhich the conduits are so bent as conduits being diagona tothe vertical and horizontal.

The invention consists in so flanging the side edges of the plates forming the conduits as to hung the joints of adjacent conduits into close relation at the extreme side edges whereby when the plates are dipped in solder to join the two plates of each pair forming a conduit theadj'acent conduits will also be soldered together at the extreme edges.

Reference is to be had to the accompanying drawings, forming a part of this s'pecifi'cation, in WlllGh similar characters of reference indicate corresponding parts in all thefigures.

Figure 1. is an elevation, partly in section, of a cooler constructed in accordance with my invention. tion on the'line 2 2 of Fi 1. Fig. 3 is an enlar ed cross-section on file line 3 3 of Fig. 1, an Fig. 4 is an enlarged detail perspective View given to better illustrate the manner of flanging the side edges of the plates.

Ordinarily in the formation of coolers having the diamond designthat, is, with the conduits running zigza instead of hav- 491 11g right-angular bendst e two plates of each conduit are equally offset to bring the joint tothe median line of the conduit. In my invention, as is most clearly shown in Figs. 1 and 4, the plates are produced with a flan e ranging diagonally to the median line of t e conduit, the letter A in Fig. 1 indicating the conduit as a whole, and the letter a,

the flanged joint.

In Figs. 2, 3, and 4 the letter B indicates one plate, and b the flanged side edge ranging diagonally to the median line between the bends.

In Figs. 2 and 3 the letters B and b represent the similar parts in Fig. 4, while the letter C represents the companion plate, and c the hookportions on thelatter, these hook pore, the bends of the Fig-2 is an enlarged cross-sec-;

tions of the plate C being return bent to enit gage the outwardly-projecting plain edges b of the companion plate,

' he present invention it should be understood, is not confined to the s ecial manner of forming the plain edges an hook portions.

Thus, as shown, the hook portions are formed on both side ed es of one plate and the plain portions on bot side edges of the companion plate; but this is immateral as far as the present invention is concerned, since any relative arran ement of the hooks and plain portions may e adopted so long-as the joint ranges diagonally to the median line between thebends, which, as will be seen most clearly in Fig. 1 at (1/, brings the flanged joints ofadjacent conduits into close contact at the extreme side ed es, because each two adjacent members (a, ig. l, b, Fig. 2) converge at the outer angle of each bendof a conduit, Whereas in previous coolers, or in like apparatus in which the conduits are zi zag, the oint has a median line parallelin t e sides of the conduit which, as will be 0 vious, leaves the conduits atthe side edges separated, the con-rduits contacting only at points some distance from the side edges, thereby necessitating the 'dipping of the cooler to a considerable de th to solder adjacent conduits to each ot er.

Having thus described my invention, I claim as new and desire to secure by Letters 'Patent- 1. A cooler or like a paratus having conduits formed with bend; to roduce circuitous passages, each conduit eing composed of a pair of plates joined at the side edges on lines diagonal to the median line of the conuit.

2. A cooler or like apparatus formed of conduits arranged to present a" diamond pattern, each conduit being formed of corrugated plates, the plates'forming a conduit being connected with each other at the side edges on lines that are disposed in each bend of the conduit diagonal to the median line of the conduit, the joints of adjacent conduits contacting with each other at the angles.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
